I have a few different router types and am confused about IOS releases. I'm using 2600 & 1700 series routers and both use a 12.x ios. Are the ios releases hardware dependent? Can anyone offer advice on keeping our ios up-to-date, but not on the bleeding edge?
TIA,
Chris

Yes.

I suggest logging onto CCO and then go to:
http://www.cisco.com/kobayashi/sw-center/sw-ios.shtml
select the IOS level and read of the deferral advisory list. If your IOS image is listed and the bug is critical, I recommend upgrading it.
I often use the hardware-software compatability matrix link for upgrades.

What I suggest if the IOS is running stable and provide the required feature then it is fine to keep it until there is a new feature you want to use that require an upgrade or bug-fix.
In normal case, upgrade IOS will not provide higher performance.
Hope this helps.
